MacBook Pro M5 Pro / Max as local AI server? Worth paying extra for Max or saving with Pro?

I’m considering getting either a 14-inch MacBook Pro with an M5 Pro and 64 GB of RAM or an M5 Max with 128 GB. Main use case for it will be software development, but also I’d like to run some local models (probably Qwen 3.5 27B / 122B, A10B / 35B-A3B), mostly for general AI workflows involving personal data that I don’t want to send to the cloud. I might also want to run some coding models together with OpenCode, although I currently use Codex and would still rely on it for most of my development work.
